v UNITED STATES PATENT OFFICE.

ABEL THOMPSON, OF BROOKLYN, ASSIGNOR TO HIMSELF, AND DANIEL RICHARDS, OF NEW YORK, N. Y.

IMPROVEMENT IN CASKS AND BARRELS FOR OIL.

Spccixication forming part ot' Letters Patent No. 37.477, dated January 20, 1863.v

To all whom t may concern Be it known that I, ABEL THOMPSON, 'of Brooklyn, in the county of Kings and State of New York, have invented, made, and applied to use a cert-ain new and useful Improvement in Barrels or Gasks for Coal-Oil, &c.; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this specification in which- Figure l represents a section longitudinally of my said barrel, and Fig. 2 isa-partial crosssection.

Similar marks of reference denote the same parts.

The amount of leakage of coal-oil, &c.,when contained in wooden barrels is so great that several attempts have been made to construct vessels entirely of metal to contain thisoil, or t0 prepare the surface of the barrels so that the oil will not soak into the wood.

The nature of my said invention consists in abarrel or cask for coal-oil,formed of wooden stayes and heads with a lining of sheet metal setting closely against the inside of said barrel or cask, by which construction the metal cyl` inder and wood barrel iit each other tightly, and there is no opportunity for the metal cylinder to move inside the barrel or ca-sk while being transported, and I make use of a screw bung-hole attached to the metal cylinder and extending through the staves, and receiving a bung or screw stopper to make the same perfectly tight, but allow for easily opening the barrel or cask without the hammering now usual, and which hammering would be liable to injure the sheet-metal lining.

In the drawings, a is a met-al cylinder (I pred fer zinc) made ofthe required size and shape,

and with the heads b b soldered tightly at the ends of said cylinder a.. The cubical contents of a barrel of this cylindrical form are very easily determined.

c is a screw bung-hole formed of sheet or cast metal, attached to the case a., and occupying a hole in one ofthe wooden staves d, or

semicircular notches in the edges of two ofthe staves. These staves are of a straight cylindrical shape when placed together, so as to correspond with the metal cylinder a, and in order to connect the cylinder a more securely to the staves of the barrel I provide small sheet-metal wings c e, soldered upon the outside ofthe cylinder c, and running up between the staves, and said wings may be tacked to one of the respective staves before the next stave is put in place. Any desired number of these wings may be employed around the barrel.

f f are t-he wooden heads of the barrel, and g g are the ordinary hoops. The staves being thicker in the middle than toward the end, there is a sufficient exterior taper to cause the hoops to drive tightly and bring the stavesI firmly to each other and to the wooden heads.

The screw c, forming the bunghole, is to be filled with any ordinary screw-plug turned by a wrench and provided with a Washer, so as to make it perfectly tight.

Vhat I cla-im, and desire to secure by Letters Patept,is-r

l. Lining a barrel or cask for petroleum or coal oils with sheet metal, said lining setting against the interior of the barrel or cask, for the purposes and as specified.

2. The niet-al screw bung-hole c, attached to the cylinder a and passing through the staves, for the purposes speciied.

3. The wings c e, attached to the cylinder a and running between the staves, for the purposes specified.

4. The staves formed as segments ot' a cylinder tapering on the outside and receiving the wooden heads and the hoops to form a barl A. THOMPSON.
